Application filed March 27, 1915. Serial No. 17,510.!

To all whom it may concern: i a Be it known that I, CLARENCE A. FULLER- won, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Window-Frames; and I do hereby. declare the following to be a full, clear,andexact description of the inventi0n,"such as will enable others skilled in the art to which it appertains to makeand usethe same.

.Thisi'invention relates to frame constructionsfor windows, and the like and more particularly to. the specific formationof the bars of which the frames .aremade- It has for anlobject to provide a composite rail in. which a series of lines of contact between the meeting members is formed to produce resistance againstflthe inward passage of cold air and the like. 1

.Further objectswill be apparent from the following specification, appended claimsand drawings in which: 1

Figure l is an elevation of portion of a window,

Fig... 2 is. a horizontal sectional view through a portion thereof, as on the line interchangeable L parts produce at compact and beneficial design in which the necessary contacting faces produce a weather tight joint. In the construction of a frame of this kind, it is necessary to have the parts thereof on the opposite sides of the pivot oppositely arranged and furthermore, in having the parts assembled as shown, the stationary and movable parts produce a completed section having a minimum cross sectional area.

Referring to the drawings, there is shown a portion of a window having the usual muntins 10 and transoms 11 in which the panes of glass 12 are disposed and in said window are sections 13 which may be swung on the axes 14 as in the usual construction. In this type of construction, the frames for the sections 13 are indicated as at 15 and are of the same general dimensions as the transoms 11.

Referring to Fig. 3 of the drawing in which the. detailed construction of the frames 15 is formed, there is shown a rail 16 which is provided with. the flange 17 against which the glass 12 is placed and saidglass is retained by a strip, 18 which may be provided across the horizontal sections with" a flange 19 to form a gutter 20 for the condensation. The rail 16 is provided with flanges 21 in which the dove-tail slots 22 are formed and tonne of the flanges a plate 23is attached in havinga dove-tail bead 24 slidably engaging the slot 22. The foregoing construction is the equivalent of the transoms 11 and remains relatively fixed with respect to the section 13, of which the frame comprises a rail 25 which is similar to the rail '16 'in having the fixed flange 26 and removable flange 27 to retain the glass .12 and the flanges 28 in which the dove-tail slots 29 are formed. One of the flanges 28 is adapted tobear against the plate 23 and the opposite flange isadapted to support a plate 30 which has a dove-tail bead 31 formed thereon to engage in the dove-tail slot 29 ofthe flange 28. The plate 30 has a face which is adapted to bear against one of the-flanges 21. Each of the rails 16 and 25 is provided with a dove-tail slot 32 in which the dove-tail bead 33 of a bar 34 is slidable, of which oneof the faces of each of these bars is beveled to present contact- .ing faces as clearly shown. Theparts of the frame tothe opposite sides of the pivot 14 are assembled in reverse positions to provide clearance in theswinging of the sec- ,tions 13. The rail 25 may be continuous about the frame and bars 33 and plates 30 may have slidable engagement with the rail 25 to present these bars and rails in the proper positions. The plate 30 may be provided with a latch 35 to which the cord 36 may be attached so that pulling the cord will release the latch 35 and cause the frame 13 toswing. This frame is returned to closed position by pulling the cord 37 which passes over the pulley 38 carried by the frame 39 which may be attached to the rail 23 adjacent to the bottom of the frame and said cord may be attached to the eye 40 which is attached to the lower rail 25. It is seen that the fixed and movable parts are of such a cross section that when these two parts are brought into bearing relation,

the cross sectional area is substantially rectangular having dimensions equal to the lengths of the sides of each of the sections independently so a minimum of space isconsumed in the construction of the frame.

;Fig. 2 of the drawing shows the frame 13- removed and the relative positions of the rails, plates and bars to the opposite sidesand a bar 4L9 withthe offset flange 50 is slidable on the bead 46. M'Various modifications may be made within the scope of this invention but in each instance, the association of a number of interohangeable parts having standard base members with standardattachments which maybe assembled in reverse positions where desired, willbe apparent and the drawings are submitted for illustrative purposes only. 'Having thus described this invention, I claim y a 1. In a structure of the'class described, a composite bar formed of continuous rails maintained in spaced relation, each of said rails having flanges formedalong the edges thereof to produce a channel structure in cross-section, said flanges having the outer faces thereof provided-with continuous un- ;dercut slots, said rails having-the adjacent faces thereof provided with continuous undercut slots formed centrally therealong, side plates carried by someof said flanges along portions of the length of said rail, said side plates having continuous enlarged beads formed thereon to engage in the -undercut slotted portion of said flanges, said side plateshaving the free edges thereof adapted to contact with the exposed faces of the-flanges of the opposite rails, central sea-ling bars carried by said rails having .ienlarged beads to engage in the continuous central slots formed along said rails, and said side plates and said central sealingbars being reversibly carried in the slotted portions of said rails.

2. In a structure of the class described, a bar of composite formation comprisingrails maintained in spaced relation, having one of said rails movable with Irespecttothe other, flanges formed along the edges of said rails, sai d"flanges having continuous undercut slots formed in theouter faces thereof, said rails having a central undercutjislot in "each ofthe adjacent faces, side plates carried bysomeof, said flanges, enlarged continuous beads formedalong said side plates adjacent to one edge thereof, said enlargedbeads engaging in some of the portions of said undercut. slots in the flanges'of the spaced rails, said side plates having the free edges thereof disposed to contact with the outer faces of the unusedfiangesof the opposite rail, said sideplates being reversibly connected to said rails, said rails havingcentral undercut slots formed therein, central sealing bars reversibly carried by said lrailsin said undercut slots, havingabeads formed thereon to engage-in said central undercut slot and said central sealing bars having contacting faces formed thereon so that when said rails are disposed in parallel relation, the side platescarried. by each member contact with portions of thdotherjrail to form a series of contacting sealingf faces between the separable parts ofthecomposite bar."

In testimony hereof I affix myv signature in presence of two witnesses. CLARENCEA FULLERTON.
